PlanDSX's 3D view feature shows the setup of the virtual lab. You can change the orientation of the view by clicking and dragging with the left mouse button. X-ray views, motion capture cameras, and other objects can be added to and removed from the scene using their respective widgets.
Ctrl-left-click on an object to select it. A trackball will be displayed over it, centered on the object's origin. You can click on and drag the trackball handles to translate or rotate the object with respect to a single axis.
When you are done moving the object, click outside the trackball or press Esc.
A square representing the floor can be added to the scene using the menu command View → Display Floor. The floor can be raised and lowered using the Up and Down keys. The global axes of the scene can be displayed using the command View → Display Axes.
